UNITED STATES PATENT OFFICE PHILIP MEDART, OF ST. LOUIS, MISSOURI,ASSIGNOR OF ONE-HALF HIS RIGHT TO WILLIAM MEDART, OF SAME PLACE.

IMPROVEMENT IN BELT-PULLEYS.

Specification forming part of Letters Patent No. 216,095, dated June 3,1879 application filed March 26, 1879.

To all whom it may concern:

Be it known that I, PHILIP MEDAR'I, of St. Louis, in the State ofMissouri, have invented certain new and useful Improvements in Belt-Pulleys; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawing, and to the letters of reference marked thereon.

This invention consists in the construction of a belt-pulley with metalhub and arms and a rim formed of bent wood, the said rim being securedto bracket-lugs formed on the ends of the arms of the pulley. Thebent-wood rim may be formed in' sections, and the ends where they meetwill be united by a dovetail lap or other joint.

The drawing is a perspective View illustratin g my invention.

A represents the hub of the pulley, and B I the arms, which may be castin one piece with the hub. These arms are provided with bracket-lugs b,to which is secured the rim C of the wheel by means of screws or rivets.

The rim is formed of wood bent to the required curvature, and the jointWhere the ends meet are dovetailed together, as shown at D.

Instead of the dovetail joint a lap or other form of joint may be used.I

The rim may be formed of one piece of wood bent into a circle, or madein any required number of sections, asdesired. After the pulley is madethe outer surface may be turned OK, so as to remove any irregularitiesthere may be in the face of the pulley.

By my invention a cheap, light, durable, and evenlyrunning pulley isformed, possessing all the advantages of a metal pulley for strength andlightness, with those of an ordinary wooden-faced pulley for traction onthe belt.

Having thus fully described my invention, what I claim is- 1. Abent-wood rim for belt-pulleys formed of a single thickness of wood, asset forth.

2. The belt-pulley wheel formed with a metal hub and arms that havetransverse bracket-lugs at their ends and a bent-wood rim, as

' and for the purpose set forth.

PHILIP MEDART.
